The Onyx Vesper

More than two years in the making.

The long anticipated Onyx Vesper has landed. The signature Onyx Racing Products sprag clutch hub is now available in a lighter and more easily adaptable format. The Vesper inherits the performance focused DNA of its predecessor without compromise. Significant revisions and tweaks on both the front and rear hubs result in a weight saving of around 156g depending on the configuration.

Let’s take a closer look

Completely revamped and better than ever.

Versatile and adaptable

Switching to pressfit endcaps means that switching between standards and freehubs has never been easier. The endcaps simply pop on and off without tools. Freehub conversions no longer require a specific axle and end cap, but utilize the same end caps. Also 6bolt and Centerlock hubs use the same endcaps!

Ceramic or Steel Bearings

The Vesper comes stock with durable stainless steel bearings. An upgrade to Verinent hybrid ceramic bearings for the hubshell is available for $60 on the front, $100 on the rear. Dual lipped seals on the exterior facing sides of the bearings keep everything sealed and protected from the elements. Service ability remains simple and accessible.

Instant Engagement

The Vesper still maintains the instant engagement and silent, drag free coasting of its predecessor. The revamped sprag configuration is lighter and utilizes less material without sacrificing performance. Those on E-Bikes and Downhill bikes are best served by the original Onyx hub which will still be available for purchase.

Lighter than the first generation Onyx hub

A complete redesign of the freehub and drive mechanism account for most of the weight savings. A smaller set of grouped sprags interface with a narrower steel contact patch on the drive axle. The reduction in the amount of stainless steel, resulted in significant weight savings. The freehub itself no longer rests on a steel axle, but utilizes a keyed interface. Once again, less steel means more weight savings.
